stares Y SNOW GUARD.

vapplication fired May 11, 1923. yseran No. 638,269.

T o all whom it 'may concern Beit known that I, ALBERT W. CAMPBELL, acitizen of the United States, residing at Hartford, in the county or"Hartford and State of Connecticut, have invented a new and usefulImprovement in Snow Guards, of which the following is a specification.

This invention relates to those articles which are designedto be appliedto the roofs of houses and other buildings that are covered with slate,tile or shingles, for the purpose of breaking up snow and ice andpreventing such from sliding off in heavy masses and causing damage.

The object of the invention is to provide a strong durable,'cheap andattractive articlek of this nature that can be quickly placed and firmlyheld in position on roofs beneath slate or shingles, which article isformed to shape without the use of rivets or the aid of solder.

This object is attained by bending and folding together pieces cut orstamped from sheet metal, desirably copper, in such manner that whenassembled the article may 'be easily slid under over-lying sections ofslate and hooked over the edge of underlying sections of slate, with theguard portion projecting outwardly in the usual manner between the slatein position to retain snow and ice.

In the accompanying drawings Fig. 1 shows a plan of an articleconstructed according to the invention. Fig. 2 is a side view of thesame. Fig. 3 is a 'bottom view. Fig. et is an end view. Fig. 5 is asection on the plane indicated by the dotted line 5 5 on Fig. 1. v

The base 1 of the guard is a stripcut from sheet metal, desirablycopper, with one end slightly reduced in width to provide shoulders 2,and the other end forked to form fingers 3. The stock between thefingers is bent under the base to form a hook 4.

The upright member of the guard, the active section 5 of which may haveany suitable cross sectional shape but which is preterably a rectangulartube as illustrated, is formed from a single strip of sheet metal,preferably copper,`bent to shape. After forming the tubular sectionofthe upright member the sides of the strip are brought togetherto formsupporting legs 6, then bent outward to provide feet designed to restupon the narrowed section of the base strip, and then the ends '8 arebent around under the narrowed section of the base so as to clamp theparts together. The shoulders 2 prevent the upright member from slidingup on the 'base strip and fingers 9 at the ends of the base strip arebent over the edges of the feet 7 so as to prevent the upright memberfrom slipping down ofi' from the base strip. In order to .stiften theupright member a brace piece 10 is arranged to stand upright across thediagonal diameter of the tubular part, which brace may ,have its loweredge bent outward to extend under one of the feet 7.

With this constructionthe parts are interlocked so that the uprightmember is rmly secured to the base member without the use of any rivets,bolts or screws and without the aid of any solder or brazing. It is asimple matter to cut the strips and fold them together in the mannerdescribed. The article constructed in this way is light yet is veryrigid and strong. ln order to put the article in position for use thefin ers at the upper end of the base are mere y slipped under the edgesof the overlying slate. It is not necessary to pry up the edges of theslate for the fingersl are thin and readily slip under them. Then thebase strip is pushed up until the hooked end under the {inge-rs snapsover the edges of the underlying slate. When the article is located inthis manner it cannot be ,dislodged so as to slide down, and the edgesof the slate eX- tending on each side of the legs of the upright sectionhold that end down and support it in such. manner that it will not bebent sidewise in either direction when it is subjected to the pressureof snow and ice that it is holding.

The invention claimed is 1. A snow guard comprising a base strip havingat one end means for retaining the article in place, and having at theother end an upwardly extending tubular section formed of a strip ofsheet metal, the ends of which are bent around and interloclred with thebase section.

2. A snow guard comprising a base strip and an upright member, saidupright member being formed of a strip of sheet metal with a tubularsection, sections extending from the tubular section and bent around thebase strip, and sections of the basey strip bent over the sections ofthe upright sections that are bent around the base strip.
